FRAMING FOR INTERNAL-COMBUSTION ENGINES.

Application filedJune 12, 1916, Serial No. 103,272. 7 Renewed April 29,1918.

To all whom it may concern:

Be it known that I, CLYDE C. TERRY, a citizen "of the United States,residing at Seattle, in the county of King and State of Washington, haveinvented a new and use ful Improvement in Framings for Internal-Combustion Engines, of which the following is a specification.

My invention relates to all types of internal combustion engines; andtheobjects of my improvement are, first, to insure perfect up by unequalexpansion of the cylinders,

the tie-beams and the bed-plate, thereby reducing the weight of metalnecessary to these parts.

I attain these objects by the mechanism illustrated in the accompanyingdrawings in which Figure 1 is an elevation showing a pair of cylinders,a tie-beam and a part of the bed-plate, with the columns connecting theabove named parts; Fig. 2 an end eleyation showing a section through thehollow longitudinal girders of the bed-plate, a section through thehollow longitudinal t1ebeam which spaces the columns and supports theguides, and a section through the cylinder block at the point at whichthe columns pass through it; and Fig. 3 a plan showing the cylinderbeams and the columns fastened to them.

Similar letters and similar figures refer to similar parts throughoutthe several views.

In this specification the words long1tud1- nal 'tie-beam andlongitudinal girder shall mean that saidtie-oeam or said girder lieparallel to the crank-shaft of the englne.

At 5 are shown two or more cylinders, each rigidly fastened, near its uper end to a pair of beams 8, by means 0 beams 12, which beams 8 and 12are all so constructed so as to allow a free circulation of cylindercooling Water around them. The aforesaid pair of beams 8 are rigidlyfastened to several columns 1 at the upper extremity of these saidcolumns 1. From the columns 1, through the said beams 8 and 12, are hungSpecification of Letters Patent.

the cylinders 5 and the Water-jacket 9. At point P where the saidcolumns 1 pass through the bottom wall 3 of the waterjacket 9 bushingand packing glands are provided thus positively spacing the cylinder andcolumns at "this point and allowing free expansion in the direction ofthe dimension X Y.

At 4: is shown a hollow longitudinal tiebeam fastened rigidly to severalof the columns 1 and supporting the crosshead-guides shown at 10.

At 7 are shown two or more hollow longitudinal girders fastened rigidlyto the crossgirders shown at 14:, to which cross-girders are rigidlyfastened the lower ends of the several columns 1, and between whichcrossgirders the crank-shaft of the engine revolves.

Both hollow lon itudinal tie-beam 4 and hollow longitudina girders 7 areprovided with means for circulating water, of the same temperature asthe water in the waterjacket 9 throughout their entire length. i

The cross-head guides shown at 10 are rigidly supported from the columns1 through single tie-beamsy15 and the aforesaid longitudinal tie-beam 4.

Now, cylinders 5, cross-head guides 10, and cross-girders 14, beingfastened rigidly to, and held-in alinement by, the several columns 1,and said several columns being positively and rigidly spaced, at the topby, beams 8, at the point P by bottom wall 3, at the point J by tie-beam4, and at the bottom by girders 7, and being spaced by these aforesaidparts only, it follows that perfect alinement will be maintained byafiording equal expansion to beams 8, bottom wall 3, tie-beam 4 andgirders 7.

As the internal combustion engine commences to operate the watercontained in water jacket 9 is heated. Beams 8 being surrounded by, andbottom wall 3 being covered by the water contained in said water jacket,these two said members expand to a degree corresponding to thetemperature of this water. At the same time, water of an equaltemperature being circulated through tie-beam 4 and girders 7, by meansof pipes 17 and 18, these two members expand equally I claim:

1. In internal combustion engines, hollow longitudinal tie beamsprovided with Water irculation and hollow longitudinal girders providedwith Water circulation, both forming part of framing supporting two ormore cylinders and two or more crosshead guides in which framing thesaid cross head guides are maintained parallel to each other and in lineWith the said cylinders by means of the equal expansion imposed upon thesaid hollow longitudinal tie beams and the said hollow longitudinalgirders by the heat from the water circulated Within them.

:2. In internal combustion engines the combination of two'or morecylinders, tWo or more beams each rigidly fastened to two or more of thesaid cylinders at a point near the upper extremity of same, a Waterjacket Within it said hollow tie beam or tie beams being rigiiillyfastened to several of the said columns, two or more cross head guideseach rigidly supported by said tie beam or tie beams, two or more hollowirders each pro vided with a means to circu ate Water Within it, andseveral cross girders each rigidly fastened to the said hollow girdersand to the bottom of two or more of the said columns, all substantiallyas and for the purposes set forth.
